Application led April 2,

This invention relates to piles and the p primary object thereof ,is to'provide an im proved form of pile which will eiiicientlyy resist attacks by salt water.

Concrete piles havefbe'en. used extensiveon the Pacific coast but they have roved because they deterlorated it is supposed, to the action of the salt water. In order to make a compile the cost must be 'kept mercial concrete down and the material of which the ordi-` nary pile is made, while having suilicient strength, is not capable of resisting theerosion of the water; Waterproof cements are known but the costs are high, so high in fact as to render them prohibitive for commer` cialuse in constructing piles.

My invention contemplates the construction of a pile which' will have all of the advantages of one constructed of water-proof cement at a very much lower cost and to this end I constructa composite pile made upl of an inner core of relatively inexpensive cement or concrete with an enveloping sheath of relatively high grade cement or concrete, the two materialsfbeing so combined as to form,

I have shown the pile as a self-sinking pile and I have shownmeans for causing the.y present pile to sink into the earth.' In the mstance the ile is self-sinking due to the fact that asu merging deviceis adapted to be detachably associatedv` therewith so that the earth ma be jetted so as to provide the necessary ole or opening for the pile. The submergin or jetting device is shown as comprising a ame which is adapted to be so associated with the pile that the earth will be removed to permit the pile to sink md thenthe submergin or'jetting frame :an be lremoved from t e pile 'to vbeused n connection with another pile.

In a pile of the class contemplated by my nvention it is important )e subjected to blows or severe external trains2 particularly shocks, because these night mjure the pile. For thls reason I pre- 'er to submerge the pile in the manner ilustrated or in an equivalent manner, it beug obvious that the exact details illustrated a this invention need not be followed for all `or form by in'efect, a homogeneous` ,tudinallyof the form.. Into the that the same not 192s. serial No.' seams. f i

as the novel advantages thereof will be apparentby reference to thepfollowing descrip-v tion -1n connection with the accompanying drawings, in which- .F1g. l 1s a vertical, longitudinal sectional vlew of a pile constructed in accordance .with my mvention showing thesubmerging 'frame 1n place. A

In carrying out my invention'I prefer to which the concrete can .be formed 4o'luuc A The construction of the invention 'as 'well' i construct a trough-shaped-.form 1, 1n which may be positioned a trough-shaped, forammous or reticulated core covering 2, about relnforcing rods or wires 3 which run longicore covering or inner form 2 is poured the core 4 of relatwely inexpensive concrete, the concrete belng poured at such a consistency, that it will extrude slightl 'through the`meshes of .the screen "to provi e projections 5, the mesh* of the screen bein suchthat these Iprojections may extend through the o erung.` 'The core will, therefore, be reinfo by the rods 3 and bythe core cover 2. en a top screen wall 6 is placed on the core within the outer form land a final sheet 7 is poured into the outer form so vthat there will be a sheathing 7 of uniform thickness about the core. The sheathing will consist of high grade concrete impervious to moisture and well adapted to resist the erosive actioifof the water as well as to resist the bores in the water. y

In the use of the word concrete Imontemplate any plastic material adapted to serve the purpose of m invention.

'When the outer sheat ing is lured-into the'outer mold or form 1, it wil fill in the space-s 8 between the projections 5, the spaces receiving similar projections on the sheathing. Therefore,

i blending together of lthe two kinds of cetroduce a loop 9 of wire therein, .portion of which projects beyond thetop at the `/seen by reference to Figs. 1 and -2. The rement or plastic compositions so that an integral mass results,

sist the action of the waterand theborers in the water, while the core is of a lower grade material, the principal virtue of whichv is strength. i

The rectangular, tubular core covering asslsts in knitting together the core and the sheathing so-that there will be no liability of the vsheathing warping or the core.

The high grade material need not extend entirely tothe bottom of the pile; just so it extends far enough below the line of scour of the river in which bed it is placed. Therefore, attention is called to Figs. 1 and breaking from v2 in which it will be seen `that the outer sheathing 7 may extend just far enough to protect the core of low grade material from the action of water or the borers above referred to. It will be seen that the sheathing 7 lconstitutes a waterproof coveringfor the.l

inner core 'of the`pile and `that all exposed portions of the pile will-be of high grade cement. I

' When the pile is being formed, I may inend of the pile so that a hook or other securing device may find means for supporting the pile when it is desired to transport the pile from place to place. A'

The lower end of thel pile is provided with a vmetallic nozzle 10, having a plurality of openings 11 therein, communicatlng with 1nclined radial passages 12 in the toe portion of the-pile, the nozzle 10 having its outlet bottom of the pile, as will be clearly spective passages or openings 12 are adapted to receive the discharge ends or nozzles 13 of a plurality of jetting pipes 14, the inbent portions 13 being received in the passages 12 and the pipes themselves-being fastene .by a frame 15, which is shown as comprising a band having offset portions 16 for the pipes, the band being hinged intermediate its ends as at 17 and secured together by the @bolt 18. The band 15 will hold the pipes flexible connections 20 to a 14 close to the pile while the pile is being sunk.

The pile is provided with a plurality of nozzles or jets 19, which are adapted to erode away the sand or dirt sothat the pile cansink into the cavity madeb the eroding action of the jetsissuing from t ie nozzles 19. The respective pipes 14 are-connectedby manifold' or hollow head 21, the hollow head'for manifold 21 having outstanding ears 22 by means of the covering of which is of a high grade material adapted to re- -shown in Fig. -1..

the loop d for the which the pipes 14 can vbe secured through the medium of the chains 24. The chains 24 are not long enough to allow the flexible connections to become broken when the manifold is raised. It will be observed by reference to Figs. 1 and 2 that there is a chain 25 connected to the manifold or head 21 so that it can be engaged by a hook 26 of a block and tackle or .hoist to permit the frame to be drawn t0 the position shown in Fig. 2, and finally pulled out of the hole. The manifold has a central opening 21 through which the loop 9 Iprojects when the pile is being sunk or when the hook 26 engages loop 9. This will be apparent by reference to Figs. 1 and 2.

The manifold or box-like casting 21 1s supplied with water through the pipe 27.

When it is desired to sink the pile, the submerging vframe is placed on the pile as f The hook 26 is then hooked under the loop 9 and the pile raised and conveyed to the point at which it is to be submerged. The point having 'been located, the pile is lowered until the point reaches the earth. lVater is then turned on so it may flow through the pipe 27 into the pipes 14,v through the passages 20 and through the nozzle 10. At the same time that the jets 19 are starting to spout water to wear away the wall of the hole being made the so that the pile may be submerged into the earth a suflicient distance, the water passing through 12 and through the nozzle 10 will cut away the bottom while the nozzles 19 will erode away the sides of the opening. When the pile has depth, the hook is released from the loop 9 and introduced across the chain 25. Then the operator may pull on the chain 25 after having removed the band 15, whereupon the pipes 14 will disassociate themselves from the pile. Then the frame can be reapplied to another pile. j v

In Fig. 5 I have shown a slightly` modified form in which outer tubes 28 corresponding to tubes 14' tubes, and separate inner tubes 29 are used nozzle tube for feeding water to the nozzle 10. In other respects thel construction shown in Fig. 5 conforms generically to the invention described in connection with Figs. 1 to 4 and 6. It will be apparent from .the foregoing that a pile constructed in accordance' wit my invention will be impervious to the action of water, that the' borers cannot tear down the outer protective skin or sheath` ing ina manner such as is quite common with present day concrete piles constructed of the ordinary material, that a pile having the protective sheathing of high grade cement or plastic material makes a very high grade pile, and since the .pile is self-sinking,

it is lobvious that there 1s no danger of the been sunk to a sufficient l are used for the jet concrete being loosened or jarred loose as would be the case in some instances where it was subjected to heavy blows.

What I claim and desire to secure by Letters-Patent is:

1. A pile having a toe portion with radial, downwardly inclined passageways surrounding a nozzle chamber with which they communicate, in combination with a submerging frame comprising a plurality of detachable pipes adapted to surround the pile and discharge into the passageways.

2. A pile having a toe portion with radial, downwardly inclined passageways surrounding a nozzle chamber with which they communicate, in combination with a submerging frame comprising a plurality of detachable pipes adapted to surround the pile and discharge into'the passageways, a manifold for the supply pipes, and flexible connections between the manifold and the pipes.

3. A pile having a toe portion with radial, downwardly inclined passageways surrounding a nozzle chamber with which they communicate, in combination with a submerging frame comprising a plurality of det-achab e pipes adapted to surround the pile andA discharge into the passageways, a manifold for the supply pipes, fiexible connections between the manifold and the pipes, and chains connecting the inlet ends of the pipes to the manifold, the chains being of less lengths than the lengths of the'exible connections.

4. A pile having a loop extending from one end thereof, the free ends of the said loop imbedded in the pile, a manifold having a cent-ral openingithrough which the loop projects, a plurality of pipes fiexibly connected to the manifold, and means for securing the pipes to the pile so that the pipes can erode the earth about the pile to provide a hole into which the pile may sink.

5. A pile having a loop extending from one end thereof, a manifold having a central opening through which the loop projects, a flexible member carried by the manifold extending across the central opening so that the loop and the flexible member may be suspended from a common support, a plurality of pipes connected to the mani old extending along the sides ofthe pile, and

inturned'ends onthe pipes to be received I in openings in the pile so that the pipes will be removably but rigidly held against the sides of the pile.

In testimony whereof I afix my signature.
